These order in the arrangement of the respective rollers may be constructed of rubber, steel or seats for an appeal to the esthetic. other suitable well-known material. 90

formed of sheet or cast metal or other suitable material, in a substantially -rectangular configuration. The track structure is provided `wlth parallel spaced-apart rails 15, 15, with lower flanges 16, 16 forming surfaces for the free support of rollers 9. V

One end of the track structure frame is open, the same being closed by end piece 20,

thereof can be arrangement is the same being secured to rails 15 by suitable means.

The top horizontal section of the track structure is provided on its under side with two parallel spaced-apart surfaces over which the rollers 10 are adapted to ride. If desired, the rollers 9 and 10, likewisethe track structure, may be formed of compressed fiber, so as torender the parts practically noiseless in operation. The closed end of the track structure and end piece 20 are provided with elastic bumpers 18 which are adapted to come in contact with the seat mountm so as to absorb the shocks and jars imparte to the parts and reduce the noise when the parts are thrust against one'another.

Each end of the track structure is provided with a spring 19 or other yielding means which is operatively associated with the seat mounting 1 so that the seat proper is normally urged tothe center. Y In this manner, and when a number of unoccupied seats are arranged, say, in a parallel row, alinement effected automatically.

that a rearrangement of the rollers and tracks would be One method of such reshown in Figure 5, whereby flanges 16 are extended inwardly to contact rollers 10, by providin a propriate clearance for rollers 9, in t e fbrm of voids or o ther suitable means, for example, corrugatlons, grooves, etc., and likewlse tracks 17 placed in contact with rollers 9.

cla-im as my invention:

1. The combination in an adjustable seat of a seat mounting having one set of four inner rollers and one set of four outer rollers rotatably .mounted and suitabl supported, and having a pivot pin depending from the body portion t ereof, adapted to be mounted in a pedestal, and a track structure having on the under side of the top horizontal section thereof two parallel spaced-apart track surfaces upon which one set having two horizontal, parallel, spaced-apart It is obvious relationship of easily possible.

tracks 17, to formof rollers ride, and.

lower track surfaces for the free support of the other set of rollers by contact with their under side, to form a broad and stable sliding mounting for aseat upon a stationary pedestal.

2. The combination in an adjustable seat of a seat mounting having a pivot pin depending from the body portion thereof, adapted to be mounted in a pedestal, and having a suitably supported pair of axles, each axle having two inner and two outer rollers rotatably mounted thereon, and a track structure having on the under side of the top horizontal section thereof two parallel spaced-apart track surfaces upon which the inner rollers ride, and having two horizontal, parallel, spaced-apart lower track surfaces for the free support of the outer rollers by contact with their under side, to form a broad and stable sliding mounting for a seat upon a stationary pedestal.

3. The combination in an adjustable seat of a seat mounting having a pivot pin depending from the body portion thereof,` adapted to be mountedin a pedestal, and having a suitably supported pair of axles, each axle having y two inner and two outer rollers rotatablv mounted thereon, and a track structure having on the under side of the top horizontal section thereof two parallel spaced-apart track surfaces upon which the outer rollers ride, and having two horizontal, parallel, spaced-apart lower track surfaces for the free support of the inner rollers by contact with their under side, to form a broad and stable sliding mounting for a seat upon a stationary pedestal.

4. In an adjustable seat, a seat mounting having a plurality of rollers rotatably mountl ed and arranged in a horizontal plane and suitably supported upon the seat mounting, and a trackstructure between which the seat mounting is interposed, said track structure being provided with upper and lower tracks,

the upper track contacting the upper surface of certain of said rollers and lower track contacting the lower surface of the other of said rollers.

-5.- In an adjustable seat, a seat mounting having a plurality of rollers rotatably mounted and arranged in a horizontal plane and suitably supported upon the seat mounting,

said seat mounting being provided with means for mounting it upon a stationary support, and aftrack structure between which the seat mounting is interposed, said track structure being provided with vupper and lower tracks, vthe upper track contacting the upper surface of certain of said rollers and lower track contacting the lower surface of the other of said rollers. 6. In an adjustable seat, a seat mounting having a plurality of rollers rotatably mounted and arranged in a horizontal plane and suitably supported upon the seat mounting, and a pivot pin depending from said seat mountin adapted to be mounted in a pedestal, an a track structure between which the seat mounting is interposed, said track structure being provided with upper andl lower s tracks, the upper track contacting the upper surface of certain of said rollers and lower track contactin the lower surface of the other of said rol ers.

In testimony whereof, I have 'aixed my lo signature.
